Canopus, the second-brightest star in the sky, is visible in this view photographed by astronaut Donald R. Pettit, Expedition Six NASA ISS science officer, on board the International Space Station (ISS). Canopus is about 300 light years from Earth in the southern hemisphere constellation Carina and is a rare class “F” yellow-white (7800 Kelvin) super giant. It is 65 times wider and 15,000 times more luminous than the Sun and is large enough to stretch three-fourths of the way across Mercury’s orbit
